Taupānga

Ko te hanga o te lactide mai i te waikawa lactic raw rauemi kei te nuinga i runga i te whakamahinga o te waikawa lactic condensation ki te whakaputa oligomers waikawa lactic, katahi ka depolymerized nga oligomers waikawa lactic me te paihikara ki te whakaputa lactide.Ko te tukanga katoa me whakahaere i raro i nga tikanga o te wera nui, te pehanga kino me te catalysis.I roto i te tukanga, ki te whakapai ake i te hua katoa, te unreactant kia whakamahia ano e reflux.Ka mutu, ka taea te whiwhi hua lactide whaimana ma etahi tikanga purenga.
Hei taonga koiora, ka whakamahia te nuinga mo te whakatikatika i nga pereti, nga tuitui pokai, nga stent ngakau, me nga whakakii tinana.
